    New Riken Keiki formaldehyde monitor from Wolflabs

    Product update

    New FP-31 formaldehyde monitor from Riken Keiki has been added. The FP-31 is a highly sensitive portable gas detector specific for formaldehyde (HCHO) detection. Unlike other Formaldehyde detection techniques that require pre-filter tubes for filtering out Phenols and other compounds, the FP-31 uses a specially doped colorimetric detection tabs with photoelectric photometry to provide a direct readout on the digital LCD display. Users place a tablet into the instrument, and then an air sample is pumped onto the tablet for either 15 minute or 30 minutes. If HCHO is present, it will cause the chemically impregnated tablet surface to darken or stain. The magnitude of the stain directly correlates to the level of HCHO in the air. The stain darkness is read by an optical sensor in the Instrument. The FP-31 calculates the gas concentration from this.
